Explanation Needs in App Reviews: Taxonomy and Automated Detection
Explainability, i.e. the ability of a system to explain its behavior to
users, has become an important quality of software-intensive systems. Recent
work has focused on methods for generating explanations for various algorithmic
paradigms (e.g., machine learning, self-adaptive systems). There is relatively
little work on what situations and types of behavior should be explained. There
is also a lack of support for eliciting explainability requirements. In this
work, we explore the need for explanation expressed by users in app reviews. We
manually coded a set of 1,730 app reviews from 8 apps and derived a taxonomy of
Explanation Needs. We also explore several approaches to automatically identify
Explanation Needs in app reviews. Our best classifier identifies Explanation
Needs in 486 unseen reviews of 4 different apps with a weighted F-score of 86%.
Our work contributes to a better understanding of users' Explanation Needs.
Automated tools can help engineers focus on these needs and ultimately elicit
valid Explanation Needs

Preface
This volumne presents the proceedings of the 1st International Workshop
on Approaches for Making Data Interoperable (AMAR 2019) and 1st
International Workshop on Semantics for Transport (Sem4Tra) held in
Karlsruhe, Germany, September 9, 2019, co-located with SEMANTiCS 2019.
Interoperability of data is an important factor to make transportation data
accessible, therefore we present the topics alongside each other in this proceedings
A Semantic-based Access Control Approach for Systems of Systems
Access control management in a System of Systems-i.e., a collaborative environment composed of a multitude of distributed autonomous organizations|is a challenging task. To answer the challenge, in this paper we propose a novel approach that incorporates semantic technologies in the Attribute-Based Access Control (ABAC) approach. Building on the basic principles of ABAC, our approach allows for a highly expressive modeling of the context in which access decisions are made, by providing mechanisms to describe rich relationships among entities, which can evolve over time. In addition, our system works in a truly decentralized manner, which makes it suitable for geographically distributed enterprise systems. We show the feasibility in practice of our approach through some experimental results
Explaining the Unexplainable
This is supplementary material to the paper "Explaining the Unexplainable]{Explaining the Unexplainable: The Impact of Misleading Explanations on Trust in Unreliable Predictions for Hardly Assessable Tasks". In an online survey experiment with 162 participants, we analyze the impact of misleading explanations on users’ perceived and demonstrated trust in a system that performs a hardly assessable task in an unreliable manner.

Explaining the Unexplainable: The Impact of Misleading Explanations on Trust in Unreliable Predictions for Hardly Assessable Tasks
To increase trust in systems, engineers strive to create explanations that are as accurate as possible. However, if the system's accuracy is compromised, providing explanations for its incorrect behavior may inadvertently lead to misleading explanations. This concern is particularly pertinent when the correctness of the system is difficult for users to judge. In an online survey experiment with 162 participants, we analyze the impact of misleading explanations on users' perceived and demonstrated trust in a system that performs a hardly assessable task in an unreliable manner. Participants who used a system that provided potentially misleading explanations rated their trust significantly higher than participants who saw the system's prediction alone. They also aligned their initial prediction with the system's prediction significantly more often. Our findings underscore the importance of exercising caution when generating explanations, especially in tasks that are inherently difficult to evaluate.
